commit 69614db1ec3d23a9e483b4832a7ef7386c6c7e99
Author: Juergen Spitzmueller <[email protected]>
Date: Sun Jul 28 15:54:55 2024 +0200
Implement LFUN_REFERENCE_TO_PARAGRAPH
This function checks whether a paragraph (specified by ID) has a label.
If so, it simply inserts a reference to this at cursor position, if
not it inserts a label to that paragraph (pos 0) and then inserts
a reference at cursor position.
Needed to implement #1624 (insert cross references to items that do not
have yet a label)
(cherry picked from commit 3fe99bf6f55858c666195263b8988165639ae7b2)
