Shawn PearceThis is a set of bash completion routines for many of the popular core Git tools. I wrote these routines from scratch after reading the git-compl and git-compl-lib routines available from the gitcompletion package at http://gitweb.hawaga.org.uk/ and found those to be lacking in functionality for some commands. Consequently there may be some similarities but many differences.
Since these are completion routines only for tools shipped with core Git and since bash is a popular shell on many of the native core Git platforms (Linux, Mac OS X, Solaris, BSD) including these routines as part of the stock package would probably be convienent for many users.
Signed-off-by: Shawn O. Pearce <spearce@spearce.org> --- I put this together rather quickly today so although I find it to work well for me and be useful, others might not. User be warned.
In particular I have found the completion of remote refs and paths within 'ref:foo/path' style arguments to be very useful, even if there is some (mild) latency involved.
