Subject: Add menu dialog helper to add rows.
X-Git-Tag: mutt-1-12-rel~52
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=042576039824d005fb500cc05786f48f50886980;p=mutt

Add menu dialog helper to add rows.

Remove the manual max calculation and dialog row allocation.

Add a NONULL check because the helper uses safe_strdup() to add a row.
