Subject: archive: add baselen member to struct archiver_args
X-Git-Tag: v1.6.0-rc0~40^2~3
X-Git-Url: https://git.tokkee.org/?a=commitdiff_plain;h=d53fe8187c38a5a160ef2199a899d9c47ec881b9;p=git.git

archive: add baselen member to struct archiver_args

Calculate the length of base and save it in a new member of struct
archiver_args.  This way we don't have to compute it in each of the
format backends.

Note: parse_archive_args() guarantees that ->base won't ever be NULL.
