Subject: Avoid nonportable ${x%%y} substitutions in DX_LINGUAS.
X-Git-Url: https://git.draconx.ca/gitweb/dxcommon.git/commitdiff_plain/19bb62393cbee31cd377d4e9bd1b493ca91528bd

Avoid nonportable ${x%%y} substitutions in DX_LINGUAS.

Using ${x%%y} substitutions is not portable: in particular it is
not supported by Solaris /bin/sh (or heirloom-sh).  Let's use a
more portable construct instead.
