"Sort the region lexicographically as specified by RECORD-REGEXP and KEY.
RECORD-REGEXP specifies the textual units which should be sorted.
For example, to sort lines RECORD-REGEXP would be \"^.*$\"
KEY specifies the part of each record (ie each match for RECORD-REGEXP)
is to be used for sorting.
If it is \"\\\\digit\" then the digit'th \"\\\\(...\\\\)\" match field from
RECORD-REGEXP is used.
If it is \"\\\\&\" then the whole record is used.
Otherwise, it is a regular-expression for which to search within the record.
If a match for KEY is not found within a record then that record is ignored.
With a negative prefix arg sorts in reverse order.
"Sort the text in the region region lexicographically.
If called interactively, prompt for two regular expressions,
RECORD-REGEXP and KEY-REGEXP.
RECORD-REGEXP specifies the textual units to be sorted.
For example, to sort lines, RECORD-REGEXP would be \"^.*$\".
KEY-REGEXP specifies the part of each record (i.e. each match for
RECORD-REGEXP) to be used for sorting.
If it is \"\\\\digit\", use the digit'th \"\\\\(...\\\\)\"
match field specified by RECORD-REGEXP.
If it is \"\\\\&\", use the whole record.
Otherwise, KEY-REGEXP should be a regular expression with which
to search within the record. If a match for KEY-REGEXP is not
found within a record, that record is ignored.
With a negative prefix arg, sort in reverse order.
The variable `sort-fold-case' determines whether alphabetic case affects
the sort order.
