Subject: Simplify some string handling in an error message.
X-Git-Tag: v9.3.0-rc1~1211^2
X-Git-Url: https://gitweb.dealii.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=refs%2Fpull%2F10800%2Fhead;p=dealii.git

Simplify some string handling in an error message.

This was triggered by the fact that the original string lacked a space after 'assign'.
