>Description:
The /usr/X11R7/libexec/ctwm_app_menu script doesn't consider whitespace around the equals sign. This causes the ctwm menu entry for pkgsrc/editors/dte to show up blank, not run when clicked, and appear in the Misc category instead of Accessories. According to

https://specifications.freedesktop.org/desktop-entry/1.1/basic-format.html#entries

there can be spaces: "Space before and after the equals sign should be ignored"
>How-To-Repeat:
Install pkgsrc/editors/dte
Restart ctwm
See the blank menu entry under Misc
