Improve the Comment strings in .desktop files

[scootergrisen]

The following strings are used in the .desktop files for LibreOffice 
that you might see in something like Xfce whisker application menu.

I suggest removing the last part of the strings because Name in the 
.desktop file might be "LibreOffice Writer" so the comment don't need to 
also have "by using Writer."

Remove:
  by using Writer.
  by using Impress.
  by using Draw.
  by using Calc.
  by using Math.
  by using Base.

 From these strings:
Create and edit text and images in letters, reports, documents and Web 
pages by using Writer.

Create and edit presentations for slideshows, meeting and Web pages by 
using Impress.

Create and edit drawings, flow charts, and logos by using Draw.

Perform calculations, analyze information and manage lists in 
spreadsheets by using Calc.

Create and edit scientific formulas and equations by using Math.

Manage databases, create queries and reports to track and manage your 
information by using Base.


Also it might be better to write something else for the Comment string 
for libreoffice-startcenter.desktop which is:

The office productivity suite compatible to the open and standardized 
ODF document format. Supported by The Document Foundation.

Seems like it is a laucher to start the 6 applications so maybe write 
something like this instead:

Create files in Writer, Calc, Impress, Draw, Math, and Base

Or:

Start center for creating files in Writer, Calc, Impress, Draw, Math, 
and Base

Or:

Start center for Writer, Calc, Impress, Draw, Math, and Base

Or whatever would be better.


I suggest not using "." at the end of the Comment-strings.



So they would end up being something like:

Create and edit text and images in letters, reports, documents and Web pages

Create and edit presentations for slideshows, meeting and Web pages

Create and edit drawings, flow charts, and logos

Perform calculations, analyze information and manage lists in spreadsheets

Create and edit scientific formulas and equations

Manage databases, create queries and reports to track and manage your 
information

Start center for Writer, Calc, Impress, Draw, Math, and Base
