-Subject: [PATCH] bin/automake: escape '{' in regexp pattern
-
-Based on perlre(1) documentation:
-.. in Perl v5.26, literal uses of a curly bracket will be required
-to be escaped, say by preceding them with a backslash ("\{" ) or
-enclosing them within square brackets ("[{]") ..
-
-References:
-https://bugzilla.redhat.com/1239379
-
-* bin/automake.in (substitute_ac_subst_variables): Escape the
-occurrence of '{' character.
