Description

Find function correctly identifies a regexp match using the digit class, but replacing with a match parameter does nothing.

Steps to Reproduce

1. New file with the following content:

0 	1 	2 	3 	4 	5 	6 	7 	8 	9
10 	11 	12 	13 	14 	15 	16 	17 	18 	19
20 	21 	22 	23 	24 	25 	26 	27 	28 	29
30 	31 	32 	33 	34 	35 	36 	37 	38 	39
40 	41 	42 	43 	44 	45 	46 	47 	48 	49
50 	51 	52 	53 	54 	55 	56 	57 	58 	59
60 	61 	62 	63 	64 	65 	66 	67 	68 	69
70 	71 	72 	73 	74 	75 	76 	77 	78 	79
80 	81 	82 	83 	84 	85 	86 	87 	88 	89
90 	91 	92 	93 	94 	95 	96 	97 	98 	99

2. Input ^([[:digit:]]+) in the find box (regexp option toggled)
3. Hit Find, all mathces are correctly identified (first row numbers)
4. Enter $1. in the replace box and hit Replace All (happens with single Replace, too)

Expected behavior:
All numbers in the first column are postpended a .

Actual behavior:
Nothing changes

Reproduces how often:
