** A new `whitespace' package has been installed, and the pre-existing one
renamed to `old-whitespace'.
Now, besides reporting bogus blanks, whitespace package has a minor mode and a
global minor mode to visualize blanks (TAB, (HARD) SPACE and NEWLINE). The
visualization is made via faces and/or display table.
The main commands are `whitespace-mode', `whitespace-toggle-options',
`global-whitespace-mode' and `global-whitespace-toggle-options'.
There are also the following useful commands: `whitespace-newline-mode',
`global-whitespace-newline-mode', `whitespace-report',
`whitespace-report-region', `whitespace-cleanup' and
`whitespace-cleanup-region'.
It has the following hook variables: `whitespace-mode-hook',
`global-whitespace-mode-hook' and `whitespace-load-hook'.
It has the following options: `whitespace-style', `whitespace-action',
`whitespace-line-column', `whitespace-display-mappings' and
`whitespace-global-modes'.
It has the following faces: `whitespace-space', `whitespace-hspace',
`whitespace-tab', `whitespace-newline', `whitespace-trailing',
`whitespace-line', `whitespace-space-before-tab', `whitespace-indentation',
`whitespace-empty' and `whitespace-space-after-tab'.
It has the following regexp options: `whitespace-space-regexp',
`whitespace-hspace-regexp', `whitespace-tab-regexp',
`whitespace-trailing-regexp', `whitespace-space-before-tab-regexp',
`whitespace-indentation-regexp', `whitespace-empty-at-bob-regexp',
`whitespace-empty-at-eob-regexp' and `whitespace-space-after-tab-regexp'.
The `whitespace-style' option specifies which kind of blanks should be
visualized. It's a list containing some or all of the following values:
trailing trailing blanks are visualized via faces.
tabs TABs are visualized via faces.
spaces SPACEs and HARD SPACEs are visualized via faces.
lines lines whose have columns beyond `whitespace-line-column' are
highlighted via faces.
Whole line is highlighted.
It has precedence over `lines-tail' (see below).
lines-tail lines whose have columns beyond `whitespace-line-column' are
highlighted via faces.
But only the part of line which goes beyond
`whitespace-line-column' column.
It has effect only if `lines' (see above) is not present in
`whitespace-style'.
newline NEWLINEs are visualized via faces.
empty empty lines at beginning and/or end of buffer are visualized
via faces.
indentation::tab 8 or more SPACEs at beginning of line are visualized
via faces.
indentation::space TABs at beginning of line are visualized via faces.
indentation 8 or more SPACEs at beginning of line are visualized, if
`indent-tabs-mode' (which see) is non-nil; otherwise, TABs at
beginning of line are visualized via faces.
space-after-tab::tab 8 or more SPACEs after a TAB are visualized via faces.
space-after-tab::space TABs are visualized when occurs 8 or more SPACEs after
a TAB via faces.
space-after-tab 8 or more SPACEs after a TAB are visualized, if
`indent-tabs-mode' (which see) is non-nil; otherwise,
the TABs are visualized via faces.
space-before-tab::tab SPACEs before TAB are visualized via faces.
space-before-tab::space TABs are visualized when occurs SPACEs before TAB via
faces.
space-before-tab SPACEs before TAB are visualized, if `indent-tabs-mode'
(which see) is non-nil; otherwise, the TABs are
visualized via faces.
space-mark SPACEs and HARD SPACEs are visualized via display table.
tab-mark TABs are visualized via display table.
newline-mark NEWLINEs are visualized via display table.
Any other value is ignored.
The `whitespace-action' option specifies which action is taken when a buffer is
visited, killed or written. It's a list containing some or all of the
following values:
nil no action is taken.
cleanup cleanup any bogus whitespace always when local whitespace is
turned on. See `whitespace-cleanup' and
`whitespace-cleanup-region'.
report-on-bogus report if there is any bogus whitespace always when local
whitespace is turned on.
auto-cleanup cleanup any bogus whitespace when buffer is written or killed.
See `whitespace-cleanup' and `whitespace-cleanup-region'.
abort-on-bogus abort if there is any bogus whitespace and the buffer is
written or killed.
