Patch 8.1.1093
Problem:    Support for outdated tags format slows down tag parsing.
Solution:   Remove FEAT_TAG_OLDSTATIC.
Files:	    runtime/doc/tagsrch.txt, src/feature.h, src/tag.c, src/version.c

+ Until March 2019 (patch 8.1.1092) an outdated format was supported:
+     {tagfile}:{tagname} {TAB} {tagfile} {TAB} {tagaddress}
+ 
+ This format is for a static tag only.  It is obsolete now, replaced by
+ the second format.  It is only supported by Elvis 1.x, older Vim versions and
+ a few versions of ctags.  A static tag is often used for functions that are
+ local, only referenced in the file {tagfile}.  Note that for the static tag,
+ the two occurrences of {tagfile} must be exactly the same.  Also see
+ |tags-option| below, for how static tags are used.
+ 
+ The support was removed, since when you can update to the new Vim version you
+ should also be able to update ctags to one that supports the second format.
