regress: replace "sed -i" with ed(1) for portable in-place editing
"sed -i" is fundamentally unportable. GNU and OpenBSD sed(1) treat the extension for the backup file as an optional argument and use "sed -i" for no backup file. FreeBSD sed(1) treats the extension as an obligatory argument and uses "sed -i ''" for no backup file. There is no single syntax that works for both. ok stsp op
use test(1) -eq and -ne to compare integers, and reduce quoting
This brings the rest of the regression test scripts in line with patch.sh.
do not skip ignored directories in 'got status' if they contain tracked files
Fixes regression introduced by commit 41f061b2f459318f3738f59d7676efccc4beb344 where tracked files inside an ignored directory were reported as missing.
sort and de-duplicate work tree path command line arguments
This is important in cases like 'got diff file.txt file.txt' which should only show the diff for file.txt once. suggested by kn@
regress: provide a sed wrapper
In order to portably handle the difference in how 'sed -i' works between *BSD and Linux, provide a wrapper to invoke the underying system sed(1) based on which OSTYPE is in use.
regress: use gdate/gln if on *BSD
To minimise the amount of churn between the difference in date(1) and ln(n) semantics, use gdate and gln from coreutils.
regress: fix test failures using ln(1)
GNU ln uses -T instead of -h for no-target-directory. OK thomas.adam
shell code fixes
Escape sequences are not handled by every echo(1), e.g. not on FreeBSD. '?' is a glob character and must be quoted. '!' is not a shell meta character. ok tracey stsp
add -s option to 'got status' which acts as a status code filter
Advantages over using grep are that the list of codes is validated against a list of known status codes, and that it is easier to match staged files which can display status codes in one or both of two columns. Prompted by feedback from krw@
