got: fix typo in argc check when diffing two blobs
We already have two arguments when diffing two blobs, so check for more than two like we do when diffing two objects to check for invalid path args. Includes new regress test by op for diffing two blobs. ok stsp@ and ok plus regress test from op@
always show commit or tree IDs in diff header, in order to help 'got patch'
The idea is that got patch can simply look for a line such as: commit - abcde1234567... to find the merge base commit ID to show in diff3 conflict markers. got log -p now displays commit IDs in its diff header, instead ofl tree or blob IDs. ok 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.
regress: make test operands POSIX compliant
Since the interpreter for the regress shell scripts are using /bin/sh this will usually imply some level of POSIX compliance (that isn't bash-specific, for instance). Some systems use dash as their sh shell and as such is stricter POSIX compliance. To help -portable, make the shell test checks use a single '=' for equality, rather than '=='.
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@
implement 'got diff -c' for diffing commits with optional filtering by path
Need for filtering by path sugggested by kn@ ok naddy@
add support for multiple path arguments to 'got diff'
positive feedback from Omar and kn ok kn
add a -q option to tests for quiet output and use it for 'make regress'
Previous default output remains when test cases are run individually. ok tracey
add submodule tests
