Text comparison in Calc occurs in
1. Formulas by operator =A1=B1 
2. Functions like MATCH etc.
3. Filters
4. Find/Replace

It is influenced by following options:
- Calc>Calculation>Case sensitive (affects 1. only)
- Calc>Calculation>Search criteria = and <> must apply to whole cells (affects
2. and 3.)
- Enable regular expressions in formulas (affects 2. only, but not 1.) Better
labeled "Enable regular expressions in function arguments"?

Filters, SortDescriptors and Find/Replace have their own options for regex and
case. There are too many options and implications. The behaviour is
inconsistent. For instance: Did anybody notice that case-insensitive cell values
obsoletes many benefits of regular expressions?

My radical proposal:
One option to toggle between native mode and compatibility mode.
Native mode:
All strings in Calc are case sensitive and support regular expressions, "=" and
"<>" do not apply to whole cells unless you use them with "^" and "$".
Compatibility mode:
Excel files are loaded in compatibility mode:
All strings are case-insensitive except for EXACT and FIND. They support
wildcards. "=" and "<>" apply to whole cells.
