* git: treat "git -C '<path>'" as a no-op when <path> is emptykn/git-cd-to-emptyKarthik Nayak2015-03-061-0/+10
| | | | | | | | | | | | 'git -C ""' unhelpfully dies with error "Cannot change to ''", whereas the shell treats `cd ""' as a no-op. Taking the shell's behavior as a precedent, teach git to treat `-C ""' as a no-op, as well.

| | | | | | | | | | | | | Instead of repeating the text to record as the commit log message and string we expect to see in "log" output, use the same variable to avoid them going out of sync. Use different names for test files in different directories to improve our chance to catch future breakages that makes "-C <dir>" go to a place that is different from what was specified.

* git: run in a directory given with -C optionNazri Ramliy2013-09-091-0/+82
This is similar in spirit to "make -C dir ..." and "tar -C dir ...". It takes more keypresses to invoke git command in a different directory without leaving the current directory: 1. (cd ~/foo && git status) git --git-dir=~/foo/.git --work-dir=~/foo status GIT_DIR=~/foo/.git GIT_WORK_TREE=~/foo git status 2. (cd ../..; git grep foo) 3. for d in d1 d2 d3; do (cd $d && git svn rebase); done The methods shown above are acceptable for scripting but are too cumbersome for quick command line invocations. With this new option, the above can be done with fewer keystrokes: 1. git -C ~/foo status 2. git -C ../.. grep foo 3. for d in d1 d2 d3; do git -C $d svn rebase; done A new test script is added to verify the behavior of this option with other path-related options like --git-dir and --work-tree.
