[Libreoffice] [PATCH] fix for fdo#40831 - Writer will crash when searching text with using regular expressions

[Tomofumi Yagi]

Hi All,

This patch will fix fdo#40831 "Writer will crash when searching text with using regular expressions".
Please review my attached patch.

Bug URL: https://bugs.freedesktop.org/show_bug.cgi?id=40831

I reproduced this bug on LibO 3.4 and 3.5.
This bug occurs when a row or column containing cursor position was removed by substitution. 
This patch is to skip the process of returning the position of the cursor,
when the row or column containing cursor position is removed.


My patch is being submitted under LGPLv3+/MPL.

Regards,
Tomofumi Yagi.
