[PATCH] web--browse: support /usr/bin/cygstart on Cygwin

["Yaakov (Cygwin/X)" <yselkowitz@users.sourceforge.net>]

From: Yaakov Selkowitz <yselkowitz@users.sourceforge.net>

While both GUI and console Cygwin browsers do exist, anecdotal evidence
suggests most users rely on their native Windows browser.  cygstart,
which is a long-standing part of the base Cygwin installation, will
cause the page to be opened in the default Windows browser (the one
registered to open .html files).
