[PATCH RESEND] perf tools: bug fix, an error of parsing 'man.<tool>.*' config variable.

[PATCH RESEND] perf tools: bug fix, an error of parsing 'man.<tool>.*' config variable.

[Taeung Song]

To add new man viewer, configs like 'man.<tool>.cmd',
'man.<tool>.path' can be set into config file (~/.perfconfig).
But parsing config file is stopped because the config variable
contains '.' character i.e.

If setting 'man.xman.cmd' into config file,

[man]
        gman.cmd = gman

when launching perf an error message is printed like below.

Fatal: bad config file line 11 in /home/taeung/.perfconfig

So modify iskeychar() function to decide '.' character
as key character parsing config file.

Not sure anyone actually uses this..

Anyway, it should be fixed since man viewer code requires it.
