4433 * For the command line, mincol is what is to be skipped over. |
| 7 | 4434 * "c" is the character typed before check_abbr was called. It may have |
| 4435 * ABBR_OFF added to avoid prepending a CTRL-V to it. | |
| 4436 * | |
| 4437 * Historic vi practice: The last character of an abbreviation must be an id | |
| 4438 * character ([a-zA-Z0-9_]). The characters in front of it must be all id | |
| 4439 * characters or all non-id characters. This allows for abbr. "#i" to | |
| 4440 * "#include". | |
| 4441 * | |
| 4442 * Vim addition: Allow for abbreviations that end in a non-keyword character. | |
| 4443 * Then there must be white space before the abbr. | |
