test: replace shebangs with descriptions in shell libraries A #! line in these files is misleading, since these scriptlets are meant to be sourced with '.' (using whatever shell sources them) instead of run directly using the interpreter named on the #! line. Removing the #! line shouldn't hurt syntax highlighting since these files have filenames ending with '.sh'. For documentation, add a brief description of how the files are meant to be used in place of the shebang line.

# Helpers for tests of git's choice of pager.
grep: Add the option '--open-files-in-pager' This adds an option to open the matching files in the pager, and if the pager happens to be "less" (or "vi") and there is only one grep pattern, it also jumps to the first match right away. The short option was chose as '-O' to avoid clashes with GNU grep's options (as suggested by Junio). So, 'git grep -O abc' is a short form for 'less +/abc $(grep -l abc)' except that it works also with spaces in file names, and it does not start the pager if there was no matching file.

t/lib-pager.sh: remove unnecessary '^' from 'expr' regular expression Regular expressions matched by 'expr' have an implicit '^' at the beginning of them and so are anchored to the beginning of the string. Using the '^' character to mean "match at the beginning", is redundant and could produce the wrong result if 'expr' implementations interpret the '^' as a literal '^'. Additionally, GNU expr 5.97 complains like this: expr: warning: unportable BRE: `^[a-z][a-z]*$': using `^' as the first character of the basic regular expression is not portable; it is being ignored Signed-off-by: Brandon Casey <casey@nrlssc.navy.mil> Signed-off-by: Junio C Hamano <gitster@pobox.com>
