Subject: Set minimal width of fixedwidth collapsable insets.
X-Git-Tag: 2.2.0alpha1~264
X-Git-Url: https://git.lyx.org/gitweb/?a=commitdiff_plain;h=7a5eff56;p=lyx.git

Set minimal width of fixedwidth collapsable insets.

Intention behind this is actually Box inset being too tiny
to reasonably contain other insets like ERT.
