[PATCH] terminal-colors.d: (man) do not show 'type' as an optional part

[Benno Schulenberg <bensberg@telfort.nl>]

That is: remove the square brackets from around 'type' in the synopsis.

Also, do not give the impression that a leading dot by itself is fine
before the 'type'.  That is: a dot is required only when 'name' and/or
'@term' is present.

Also, do not colorize the square brackets as if they were part of the
placeholders.  (And use ++double plus++ passthroughs for the opening
square brackets, to prevent asciidoctor from misinterpreting them.)

Indent the list of file types, for clarity.

And correct or improve some wordings, and remove an inconvenient
blank line in an example.

 *disable*::
 Turns off output colorization for all compatible utilities. See also the NO_COLOR environment variable below.
 *enable*::
 Turns on output colorization; any matching *disable* files are ignored.

 Specifies colors used for output. The file format may be specific to the utility, the default format is described below.

 If there are more files that match for a utility, then the file with the more specific filename wins. For example, the filename "@xterm.scheme" has less priority than "dmesg@xterm.scheme". The lowest priority are those files without a utility name and terminal identifier (e.g., "disable").
