remove overquoting from test titles

[Paul Eggert]

I installed this to eliminate some unnecessary [ ] in the test suite output:

2005-02-05  Paul Eggert  <address@hidden>

        * tests/foreign.at (Libtool): Don't overquote AT_SETUP arg.
        * tests/m4sh.at (AS_DIRNAME, AS_BASENAME, AS_MKDIR_P, AS_HELP_STRING):
        Likewise.
        * tests/semantics.at (AC_C_BIGENDIAN, AC_PATH_PROG & AC_PATH_PROGS):
        Likewise.
