KDevelop misses the option to open a file on a specific line. This is essential for one-click setups like http://pla.nette.org/en/how-open-files-in-ide-from-debugger#toc-linux

Almost every editor offers that option, e.g. --line NNN in Kate or +NNN in Vim. KDevelop uses :NNN which seems to be broken.

Reproducible: Always

Steps to Reproduce:
On the command line, try to open a file in KDevelop and immediately jump to a specific line.



Actual Results:  
$ kdevelop myfile:10 

opens myfile on line number 11 (!). Looks like a classical off-by-one-mistake ;)
... but only if KDevelop is not already running. 

When KDevelop is already running, each time you do that, it opens the file again in a new tab and places the cursor in line number 1.

Expected Results:  
KDevelop should offer a command line option like the ones described above that makes it open a file and places the cursor on the given line. 

If the file is already open in a tab, KDevelop should NOT open it again, but simply bring its tab to the front and then place the cursor on the given line.
