Subject: Fix return value for rfc822_write_address()
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=2875fe0d32c5bd93dbb3db1c59fce308aaa9adc3;p=neomutt

Fix return value for rfc822_write_address()
The strcat cleanup changed the return type from void to int but didn't
provide a return value for the case of bogus function arguments.
