Subject: Add --stdout option to export
X-Git-Tag: v0.14.3~541
X-Git-Url: https://git.distorted.org.uk/~mdw/stgit/commitdiff_plain/1fceece7011fb0c32181d4e2128a871b09651b01

Add --stdout option to export

This option allows the 'export' command to write the patches to the
standard output. Useful for reviewing patches without writing them to
files.
