remove extra new lines from #warning and #pragma deprecated

Browse Source 
The `#warning` and `#pragma deprecated` directives print the new line characters which are part of the user entered string. As the message formats for both these already contain a new line character at the end, the aforementioned directives printed two new lines.

This commit adds code to discard the new line characters from user string.
