[orca-list] I hopefuly fixed an I18n related bug with orca --help outputs related

[Hammer Attila <hammera pickup hu>]

Hy,

When I looked the orca --help output in gnome-terminal, a string is not 
marked for translation with end of output before the report bugs part, 
and some strings is partialy marked for translation.
For example some option is using after the equals character the 
"filename" string, but the problem for example hungarian language we 
always spokening filename with "fájlnév" word, similar the dirname word 
with "könyvtárnév" word with translated applications.
This all problems fixed my patch, please look and if my patch is good, 
please commit.
The link is following:

Note: the original english help outputs is fit always in gnome-terminal 
window without wrapping near middle a word? I using the hungarian 
translation some places with \n simbols, but I don't no possible 
verifying the english output with terminal for example the |more command 
part.
Select all and paste for example gedit is not good, because Gedit 
wrapping longer lines.
