[issue27619] getopt should strip whitespace from long arguments

[Serhiy Storchaka]

Serhiy Storchaka added the comment:

C getopt doesn't strip trailing spaces. What you mistook for stripping trailing spaces is actually a feature of GNU getopt that allows you to use shortened variant of long option.

$ ./getopdemo "--  sp" 1 --eg 2 "--  ch" 3
option   spam   with arg 1
option eggs   with arg 2
option   cheese with arg 3
