Subject: cvsexportcommit -p : fix the usage of git-apply -C.
X-Git-Tag: v1.5.1.1~5
X-Git-Url: https://git.tokkee.org/?a=commitdiff_plain;h=fc1f458c3506ea3f76a328f10b4008c45af32c4b;p=git.git

cvsexportcommit -p : fix the usage of git-apply -C.

Unlike 'patch --fuzz=NUM', which specifies the number of lines allowed
to mismatch, 'git-apply -CNUM' requests the match of NUM lines of
context.  Omitting -C requests full context match, and that's what
should be used for cvsexportcommit -p.
