[gdb/ChangeLog]
2004-09-10  Jason Molenda  (jmolenda@apple.com)

        * cli/cli-script.c (read_next_line): Accept zero or more whitespace
        chars after 'if' or 'while' commands in user-defined commands.

[gdb/testsuite/ChangeLog]
2004-09-10  Jason Molenda  (jmolenda@apple.com)

        * gdb.base/define.exp: Two new tests to verify zero space chars
        after 'if' and 'while' commands in a user-defined command is correctly
        parsed.
