cursor placement [#110, replaces pr #63]

[olets]

Features

• abbr-expand-and-space is deprecated. Use abbr-expand-and-insert instead
• If ABBR_SET_EXPANSION_CURSOR (default 0) is non-zero, the expansion's first instance of ABBR_EXPANSION_CURSOR_MARKER (default $ABBR_LINE_CURSOR_MARKER) will be replaced with the cursor.
• If ABBR_SET_LINE_CURSOR (default 0) is non-zero, and the cursor was not placed during expansion, the line's first instance of ABBR_LINE_CURSOR_MARKER (default %) will be replaced with the cursor

Tips

1. Add the ABBR_EXPANSION_CURSOR_MARKER to end of an expansion to opt out of inserting a space

   % ABBR_SET_EXPANSION_CURSOR=1
   % abbr nospace=none%
   % nospace[SPACE] # expands to `none[CURSOR]`

2. Build "template-y" abbreviations by including multiple ABBR_LINE_CURSOR_MARKER's in an expansion

   % ABBR_SET_EXPANSION_CURSOR=1
   % ABBR_SET_LINE_CURSOR=1
   % abbr template="a%b % c%d"
   % template[SPACE] # expands to `a[CURSOR]b % c%d`
   % a[type xSPACE]b % c%d # cursor moves: `ax b [CURSOR] c %`
   % ax b [type ySPACE] c%d # cursor moves: `ax b y c [CURSOR]`
   % ax b y c [CURSOR]

3. If your expansions have %, consider changing ABBR_LINE_CURSOR_MARKER to %ABBR_CURSOR% or similar
