3281 * FIND_IDENT: find an identifier (keyword)
3282 * FIND_STRING: find any non-white string
3283 * FIND_IDENT + FIND_STRING: find any non-white string, identifier preferred.
3284 * FIND_EVAL: find text useful for C program debugging
3285 *
3286 * There are three steps:
3287 * 1. Search forward for the start of an identifier/string. Doesn't move if
3288 * already on one.
3289 * 2. Search backward for the start of this identifier/string.
3290 * This doesn't match the real Vi but I like it a little better and it
3291 * shouldn't bother anyone.
3292 * 3. Search forward to the end of this identifier/string.
3293 * When FIND_IDENT isn't defined, we backup until a blank.
3294 *
3295 * Returns the length of the string, or zero if no string is found.
3296 * If a string is found, a pointer to the string is put in "*string". This
3297 * string is not always NUL terminated.
