patch 8.0.0234: crash when using put in Visual mode
Problem: When several lines are visually selected and one of them is short,
using put may cause a crash. (Axel Bender)
Solution: Check for a short line. (Christian Brabandt)

6 " Details of the CWEB language can be found in the article by Donald E. Knuth | |
7 " and Silvio Levy, "The CWEB System of Structured Documentation", included as | |
8 " file "cwebman.tex" in the standard CWEB distribution, available for | |
9 " anonymous ftp at ftp://labrea.stanford.edu/pub/cweb/. | |
10 | |
11 " TODO: Section names and C/C++ comments should be treated as TeX material. | |
12 " TODO: The current version switches syntax highlighting off for section | |
13 " TODO: names, and leaves C/C++ comments as such. (On the other hand, | |
14 " TODO: switching to TeX mode in C/C++ comments might be colour overkill.) | |
