Parse failure with AM designator as leading substring of PM designator

[GoogleCodeExporter]

Suppose you have a culture with an AM designator of "Foo" and a PM designator 
of "FooBar". Currently if we format 4pm as "4 FooBar" and then try to parse it, 
we'll parse the "4 Foo" and then think we've finished.

We should do the longest-match as per other text fields such as month and day 
of week.

Was this only a theoretical problem, or are there actual cultures that behave 
like this?

It's a real problem in Mono 3.0, in Cambodia IIRC (definitely some culture). 
I'd never have spotted it otherwise, but I wanted to make sure we tested it 
either way :)
