Fix misparsing of -remote URLs containing parenthesis (bug 830)

Be more strict about the format accepted by the ELinks specific extension
to the -remote URL syntax. That is, commands must begin with a nonempty
sequence of ASCII alphabetic characters followed by optional whitespace and
an opening parenthesis. Also, document the syntax.

Fixes bug 830.

instance, but instead connects to an already running ELinks, making it
possible to control that ELinks instance. The -remote command line switch
takes a command consisting of the action to invoke and any parameters to the
action. Here is an example for opening freshmeat.net in a new tab:

characters followed by optional whitespace and an opening parenthesis. They
must end with a closing parenthesis optionally followed by whitespace. Here is
