+ Fix bug #15766 (/KEEP subcommand on SAVE doesn't fully support
+ ALL) and additional underlying system file issues.
+
+ Thanks to John Darrington for review.
+
+ First problem: var_hash points to variables not owned by the
+ sys-file-reader, which the caller may free or modify. Use an
+ array of sfm_vars instead, as done earlier (e.g. CVS version
+ 1.12).
+
+ * sys-file-reader.c (struct sfm_reader): Remove var_hash, svars
+ members and remove all code that references it. Add vars, var_cnt
+ members. Remove fix_specials member, which was unused.
+ (struct sfm_var) Remove name member, which was unused.
+ (sfm_close_reader) Free vars member instead of var_hash.
+ (compare_var_shortnames) Removed.
+ (hash_var_shortname) Removed.
+ (sfm_open_reader) Fill out vars array.
+ (compare_var_index) Removed.
+ (sfm_read_case) Use vars instead of var_hash.
+
+ Second problem: we're confused about when we actually have very
+ long strings, causing us to choose incorrectly between slow path
+ and fast path in sfm_read_case.
+
+ * sys-file-reader.c: (sfm_open_reader) Only mark has_vls if we
+ have very long strings, not when we have long variable names,
+ which is an unrelated feature.

+
+ * variable.h: Move var_set and variable parsing declarations to
+ new header, src/language/lexer/variable-parser.h. Modified lots
+ of files to include the new header.
