Subject: Make bash completion fail to bashdefault before default completion.
X-Git-Tag: v0.15-rc1~50
X-Git-Url: https://git.distorted.org.uk/~mdw/stgit/commitdiff_plain/e799c7fa7f55b27d78f5bccdddb86f78260bf955

Make bash completion fail to bashdefault before default completion.

If "-o bashdefault" isn't possible, use old "-o default" only.

(this patch inspired by similar mechanism in Mercurial bash completion
script)
