fcm make: Error parsing contractions in comments

[ScottWales]

FCM is ignoring lines that have an apostrophy in an inline comment

$foo = -a # Can't use contractions!
build.prop{fc.flags} = $foo

I expect that FCM will use the flag -a, however no flags actually get used

$ cat fcm-make-as-parsed.cfg
build.prop{fc.flags} = 

Per http://metomi.github.io/fcm/doc/user_guide/annex_cfg.html#syntax.comment any characters on a line after the # should get ignored. If you add a second apostrophy to the comment it gets parsed correctly

$foo = -a # ''
build.prop{fc.flags} = $foo

$ cat fcm-make-as-parsed.cfg 
build.prop{fc.flags} = a
