Merge branch 'jc/decorate-leaky-separator-color'

"git log --decorate" did not reset colors correctly around the
branch names.

* jc/decorate-leaky-separator-color:
log --decorate: do not leak "commit" color into the next item
Documentation/config.txt: simplify boolean description in the syntax section
Documentation/config.txt: describe 'color' value type in the "Values" section
Documentation/config.txt: have a separate "Values" section
Documentation/config.txt: describe the structure first and then meaning
Documentation/config.txt: explain multi-valued variables once
Documentation/config.txt: avoid unnecessary negation

+ Values
+ ~~~~~~
+ 
+ Values of many variables are treated as a simple string, but there
+ are variables that take values of specific types and there are rules
+ as to how to spell them.
+ 
+ boolean::
+ 
+        When a variable is said to take a boolean value, many
+        synonyms are accepted for 'true' and 'false'; these are all
+        case-insensitive.
+ 
+        true;; Boolean true can be spelled as `yes`, `on`, `true`,
+               or `1`.  Also, a variable defined without `= <value>`
+               is taken as true.
+ 
+        false;; Boolean false can be spelled as `no`, `off`,
+               `false`, or `0`.
+ +
+ When converting value to the canonical form using '--bool' type
+ specifier; 'git config' will ensure that the output is "true" or
+ "false" (spelled in lowercase).
+ 
+ integer::
+        The value for many variables that specify various sizes can
+        be suffixed with `k`, `M`,... to mean "scale the number by
+        1024", "by 1024x1024", etc.
+ 
+ color::
+        The value for a variables that takes a color is a list of
+        colors (at most two) and attributes (at most one), separated
+        by spaces.  The colors accepted are `normal`, `black`,
+        `red`, `green`, `yellow`, `blue`, `magenta`, `cyan` and
+        `white`; the attributes are `bold`, `dim`, `ul`, `blink` and
+        `reverse`.  The first color given is the foreground; the
+        second is the background.  The position of the attribute, if
++       any, doesn't matter. Attributes may be turned off specifically
++       by prefixing them with `no` (e.g., `noreverse`, `noul`, etc).
+++
++Colors (foreground and background) may also be given as numbers between
++0 and 255; these use ANSI 256-color mode (but note that not all
++terminals may support this).  If your terminal supports it, you may also
++specify 24-bit RGB values as hex, like `#ff0ab3`.
+ +
+ The attributes are meant to be reset at the beginning of each item
+ in the colored output, so setting color.decorate.branch to `black`
+ will paint that branch name in a plain `black`, even if the previous
+ thing on the same output line (e.g. opening parenthesis before the
+ list of branch names in `log --decorate` output) is set to be
+ painted with `bold` or some other attribute.
