rev. 108 - button labels - is it correct to take one string from translation table in more files?

Description

Tom,

I commited 2 files proj.inc.php and file.inc.php change in revision 108.
Button label at upload file was hardcoded as "Send file".
I changed it to __('Upload') string as in taskView.inc.php.
Is it correct, or should I add two new strings to translation table?
