As said by Wolfgang, you may infer that I use Emacs as my preferred text editor, which knows about the double space. Citing from the info file: The sentence commands assume that you follow the American typist's convention of putting two spaces at the end of a sentence; they consider a sentence to end wherever there is a `.', `?' or `!' followed by the end of a line or two spaces, with any number of `)', `]', `'', or `"' characters allowed in between. A sentence also begins or ends wherever a paragraph begins or ends. It is useful to follow this convention, because it makes a distinction between periods that end a sentence and periods that indicate abbreviations; that enables the Emacs sentence commands to distinguish, too. These commands do not stop for periods that indicate abbreviations. So I really ask you to reconsider your critique. >> +int rtc_get(struct rtc_time *tm) >> +{ >> + int rel = 0; >> + uchar buffer[7]; >> + >> + memset(buffer, 0, 7); >> + >> + /* Read 52 bits into our buffer */ >> + tws_read(buffer, 52); >> + >> + tm->tm_sec = BCD2BIN( buffer[0] & 0x7F); >> + tm->tm_min = BCD2BIN( buffer[1] & 0x7F); >> + tm->tm_hour = BCD2BIN( buffer[2] & 0x3F); >> + tm->tm_wday = BCD2BIN( buffer[3] & 0x07); > ------------------------------^ > please, remove space here. Are you sure? You may notice that the spaces are intentional and *actually improve* the readability. >> + tm->tm_mday = BCD2BIN((buffer[3] & 0xF0) >> 4 | (buffer[4] & 0x0F) << >> 4); >> + tm->tm_mon = BCD2BIN((buffer[4] & 0x30) >> 4 | (buffer[5] & 0x0F) << >> 4); >> + tm->tm_year = BCD2BIN((buffer[5] & 0xF0) >> 4 | (buffer[6] & 0x0F) << >> 4) + 2000; > > these tree lines above are too long. Oh well. I really checked CodingStyle in the Linux kernel and it has this to say: The only exception to this is where exceeding 80 columns significantly increases readability and does not hide information. So please reconsider your critique with this sentence in mind.

Ok, I don't have a problem with that. I will not fix however, because I actually realize that this is another leftover of the previous implementation which did not use the tws protocol driver, so I remove the lines entirely.
