Subject: Work around compilation warning
X-Git-Tag: 2.4-beta2~1133
X-Git-Url: https://git.lyx.org/gitweb/?a=commitdiff_plain;h=c242b2536401dc06ab5740d6c9c01013282ed795;p=lyx.git

Work around compilation warning

Clang 12 (at least) misses the fact that tag is always initialized,
because the if/else sequence does cover all cases.

Initialize the variable although it is not required. It does not hurt
at least.
