Whitespace and config values

[Bryan Blackburn]

Does anyone see any issue with the attached patch?  It seems that parsing
macports.conf will leave trailing whitespace on values, hence some things
won't match "yes" because they are "yes	" (see ticket #18460).  I ask in
case someone is aware of any possible reason to keep trailing whitespace
within values...
