Semantics change. If a variable is followed by a mixture
of text and regular expressions, that whole mixture is
considered to follow the variable and used for matching.
The earlier semantics change whereby a single unescaped
space denotes the regular expression / +/ broke the
simple case @a word. It caused the @a to be followed
not by the text " word" but by just the regular expression
element.
With this change @a word means that a is followed by
the regex / +/ and "word".
* match.c (text_s): New symbol variable.
(h_text): New function.
(syms_init): Initialize new symbol variable.
(dir_tables_init): Hook h_text into horizontal directives table.
* match.h (text_s): Declared.
* parser.y (text, texts): New nonterminals.
(elem): TEXT, SPACE and regex are now handled under texts
grammar production. All texts are run together and produce
an item which looks like (text items ...).
* txr.1, RELNOTES: Updated.
* txr.c (remove_hash_bang_line): Updated to find #! buried
in (text ...) syntax.
