Subject: nmbug: allow empty prefix
X-Git-Tag: 0.16_rc1~193
X-Git-Url: https://git.notmuchmail.org/git?p=notmuch;a=commitdiff_plain;h=16bf7b4b89b5ceb7f13ed318051ecd7c629d582b;hp=f7a7f78aebd7f0571cad7f4813ef18dac5247c73

nmbug: allow empty prefix

Current code does not distinguish between an empty string in the
NMBPREFIX environment variable and the variable being undefined. This
makes it impossible to define an empty prefix, if, e.g. somebody wants
to dump all of their tags with nmbug.
