Fragment parsing

[Dieter@isodraw.de (Dieter Weidenbrueck)]

Lofton et al,

according to the latest changes a lot more characters may show up in IDs or
names.

Especially the name attribute is not restricted with regard to usage of the
space character.

Consider the following fragments:

#name(myName,view_context)
#name(myName ,view_context)
#name( myName ,view_context)
#name( myName,view_context)

These are four variations of a name with and without spaces as the first
and/or last character.
Right now, these are four DIFFERENT names, i.e. the names are in quotes:

"myName"
"myName "         space at end is part of name
" myName "        spaces at start and at end are part of name
" myName"         space at start is part of name

Is this the desired behavior for everybody, or should there be a rule that
disallows leading and/or trailing spaces?

BTW, this problem does not exist with IDs because the space is prohibited
there.
