* src/dispextern.h (struct it) : Removed extend_face unneeded members.
* src/xdisp.c (handle_face_prop_general) : renamed to face_at_pos and
removed input parameter initial_face_id. Updated all occurrences.

Update all the occurrences in src/xdisp.c and src/xfaces.c

* lisp/hl-line.el : Added extend attribute to hl-line face.

 * src/xdisp.c (append_space_for_newline): Small code refactor and
 simplification.

* src/xdisp.c (append_space_for_newline): Modified to add the space
with the last face also in terminal interface.
(fill_column_indicator_column): Modified to group more conditions.
(extend_face_to_end_of_line): Simplified code in
fill_column_indicator to use the new function.

* src/xdisp.h (handle_face_prop_general): Changed function prototype
to receive different arguments.

The face used in extend_face_to_end_of_line is not the same than in
the text before anymore.
The display engine uses the :extend parameter in the faces to
conditionally merge and create a new id if needed.

This is an initial change to add a parameter :extend that will be used
in the display engine later.

    * src/dispextern.h (enum face_underline_type): Add FACE_NO_UNDERLINE = 0.
    (struct face): Merge `underline_type` and `underline_p` into `underline`.
    Update all the occurrences in src/xdisp.c, src/xfaces.c, and src/xterm.c.

* doc/misc/ert.texi (Running Tests in Batch Mode): Say that ert test
selector strings are regular expressions.

At the same time, remove the 2-character left margin.

* lisp/progmodes/compile.el (compilation-set-up-arrow-spec-in-margin): put
compilation-tear-down-arrow-spec-in-margin onto change-major-mode-hook.

It was an internal symbol in the old `rx' implementation, used in old
versions of the `flycheck' package.

* lisp/image/image-converter.el (image-converter--converters):
Move ImageMagick last in the list.

* lisp/calc/calcalg2.el (math-try-solve-for):
To solve Ax^n=0 where A is a nonzero constant and x the variable to
solve for, solve x^n=0 instead of solving A=0 (which obviously fails)
or something equally stupid.
* test/lisp/calc/calc-tests.el (calc-test-solve-linear-system): New.

* doc/emacs/files.texi (File Conveniences): Move bit about
convert-images-externally to user manual from lispref manual.

* lisp/image/image-converter.el (convert-external-images): Remove
defcustom that was accidentally not removed when moving to
image.el (and renamed).

* lisp/calendar/iso8601.el (iso8601--time-match): The fraction
mark can be either . or , and there can be arbitrarily many digits
in the fraction.

* lisp/gnus/gnus-start.el (gnus-group-change-level): Ensure that
all new groups are in gnus-active-hashtb so that they can be
completed to.

takes a DEFS parameter (bug#20319).

* time-stamp-tests.el: Group tests by when the format was or will be
documented.  Add tests for a few more undocumented, volatile formats.
Change AM hours test time to be a different hour from PM test time.
(Making these changes to the tests now will minimize test changes
needed later with anticipated code changes.)
