mysql lets me login even if i press CTRL-C

1) I invoke mysql with an ampty -p parameter
2) I write the password, but I DONT press enter
3) I press ctrl-c
4) I'm logged in, as if I pressed enter

This does not happen always - it depends how I invoke mysql. However, using the default Icon in the Win's start menu, this happens.

Example:

C:\Programmi\MariaDB 5.5\bin>mysql "--defaults-file=C:\Programmi\MariaDB 5.5\dat
a\my.ini" -uroot -p
Enter password: *****
