Whitespace in \c[...], \x[...], etc.

[Helmut Wollmersdorfer]

It's not explicitly specified, if insignificant whitespace is allowed in 
\c[...], \x[...], etc.

Std.pm allows e.g.
  "\x[   41  ,   42  ,  43  ]"

For convenience - especially with long charnames - it should be possible 
to write

"\c[
    SPACE,                 # blafasel
    LATIN SMALL LETTER A,  # some comment
    COMBINING DOT BELOW,   # thisandthat
]"
