Does comment style affect binary size?

Question

I am getting started to the embedded system's world. During this journey I came across to a "different" way to comment functions:

ISR(INT0_vect) {         /* Run every time there is a change on button*/

I particularly prefer something like:

// Run every time there is a change on button
ISR(INT0_vect) {

Is it just a "taste thing" or by commenting like that I can "save" some EEPROM space in my ATMEGA168A?

Comments are stripped by the preprocessor. So the "*compiler*" never cares about them because they never reach the compiler. — Iharob Al Asimi, Jan 05 '16 at 18:48
Unless your *source code* is being stored in the EEPROM, style of commenting doesn't matter; comments are not preserved in the generated machine code in any form. — John Bode, Jan 05 '16 at 18:55

The style of comments is purely an aesthetic concern. Compilers disregard all comments in your code when generating an object file, so how you format comments will have no bearing on EEPROM space.
