commit 6aee9660b9bac6305e787deb02a260afa4f84dbf
Author: G. Branden Robinson <[email protected]>
AuthorDate: Tue Mar 31 19:06:19 2026 -0500
[mm]: Regression-test Savannah #68201.
Add regression test for Savannah #68201. The `IA` and `WA` macros
disable the escape character (and `IE` and `WE` reënable it). This
however is not compatible with DWB 3.3 mm, and makes support of these
macros in non-English locales needlessly difficult.
* contrib/mm/tests/IA-IE-WA-WE-allow-escape-sequences.sh: Do it.
* contrib/mm/mm.am (mm_TESTS): Run test.
Test fails at this commit.
