git mv *.hint -> README.md

There is one exception:

    $ find . -name '*.hint' -execdir git mv '{}' README.md \;
    git statufatal: destination exists, source=1992/albert/albert.hint, destination=1992/albert/README.md

Looking at the two files they differ quite a bit so I've not changed it.
I'll bring this up on GitHub.

+    To use:
+	make esde
+
+    Try: 
+	esde esde.data Johanson
+	esde esde.data2 read
+	esde esde.hint date
+
+    In general:
+
+	esde data-file word
+
+    where data-file contains lines of < 255 chars in length.

+Selected notes from the author:
+
+    0) what this program does.
+       This program searches in the file words which have the same Soundex code
+       like the given word, and print out lines with these words.
+
+       The Soundex code is using to find similar sounds words.
+
+       Soundex code begins with the first letter of the word followed by a
+       three-digit code. There is the algorithm:
+
+       a) Every letter in the word change by a digit (excluding the first
+          letter).
+       b) Replace all pairs of the same code by single code
+          (ex. R011235 -> R01235).
+       c) Remove all 0-codes (ex. R01235 -> R1235).
+       d) If lenght of code is > 4, get only first 4 codes (ex. R1235 -> R123).
+       e) If lenght of code is < 4, add zeros (ex. T12 -> T120).
+
+       There is the codes:
+              0  =  A, E, H, I, O, U, W, Y
+              1  =  B, P, F, V
+              2  =  C, S, G, J, K, Q, X, Z
+              3  =  D, T
+              4  =  L
+              5  =  M, N
+              6  =  R
+
+    1) information about an info file.
+       An info file should be a text file consisting of lines (max. 256 bytes
+       in each line).
