/* If EOL is not-NULL query the SVN_PROP_EOL_STYLE property on file
LOCAL_ABSPATH in DB. If STYLE is non-null, set *STYLE to LOCAL_ABSPATH's
eol style. Set *EOL to
- NULL for svn_subst_eol_style_none, or
- a null-terminated C string containing the native eol marker
for this platform, for svn_subst_eol_style_native, or
- a null-terminated C string containing the eol marker indicated
by the property value, for svn_subst_eol_style_fixed.
If STYLE is null on entry, ignore it. If *EOL is non-null on exit,
it is a static string not allocated in POOL.
If KEYWORDS is not NULL Expand keywords for the file at LOCAL_ABSPATH
in DB, by parsing a whitespace-delimited list of keywords. If any keywords
are found in the list, allocate *KEYWORDS from RESULT_POOL and populate it
with mappings from (const char *) keywords to their (svn_string_t *)
values (also allocated in RESULT_POOL).
If a keyword is in the list, but no corresponding value is
available, do not create a hash entry for it. If no keywords are
found in the list, or if there is no list, set *KEYWORDS to NULL.
If SPECIAL is not NULL determine if the svn:special flag is set on
LOCAL_ABSPATH in DB. If so, set SPECIAL to TRUE, if not, set it to FALSE.
If PROPS is not NULL, use PROPS instead of the properties on LOCAL_ABSPATH.
If WRI_ABSPATH is not NULL, retrieve the information for LOCAL_ABSPATH
from the working copy identified by WRI_ABSPATH. Falling back to file
external information if the file is not present as versioned node.
If FOR_NORMALIZATION is TRUE, just return a list of keywords instead of
calculating their intended values.
Use SCRATCH_POOL for temporary allocation, RESULT_POOL for allocating
*STYLE and *EOL.

only the KEYWORD_LIST input parameter is needed. (And there is no
need to print "-1" as the revision value.)
