More H'00 support

[Cecilia Rodrigues]

Hi, 

The '-h-tick-hex' assembler option has been added to gas to support
H'00 syntax for hex constants. However, I have observed a strange 
behaviour while using this option. The assembler did not complain
when '-h-tick-he' is used instead of '-h-tick-hex'. I further 
checked that the assembler accepts the following other incorrect
options without generating any error message,
'-h-', '-h-t', '-h-tick-' etc.
