commit 77f6ba2a4ec8ef48d94004aefb5bc0efa6bd5a2b
Author: G. Branden Robinson <[email protected]>
AuthorDate: Fri Dec 5 05:33:16 2025 -0600
[troff]: Fix Savannah #67771.
* src/roff/troff/input.cpp (define_class_request): Stop warning on
trailing space after arguments to `class` request. Populate local
variable `child1` (which helps us keep track of range expressions)
only if the current token is a kind of character.
Fixes <https://savannah.gnu.org/bugs/?67771>. Problem appears to date
back to commit 1cb8dd7bde, 13 December 2010.
