[PATCH] Add -k kill keyword expansion option to git-cvsimport - revised
Early versions of git-cvsimport defaulted to using preexisting keyword
expansion settings. This change preserves compatibility with existing cvs
imports and allows new repository migrations to kill keyword expansion.
After exploration of the different -k modes in the cvs protocol, we use -kk
which kills keyword expansion wherever possible. Against the protocol
spec, -ko and -kb will sometimes expand keywords.
Should improve our chances of detecting merges and reduce imported
repository size.
